Dragonfly device study for functional mitral valve leakage
Part of Heart & circulation clinical trials.
This trial tests a catheter-based procedure (putting a small device through blood vessels) to repair a leaking mitral valve caused by heart muscle problems. It aims to reduce symptoms and improve heart function and safety in people who are still having heart failure symptoms despite standard treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You have symptomatic functional mitral regurgitation (mitral valve leakage caused by heart muscle weakness) and it must be confirmed on an echocardiogram—without signs of “degenerative” valve damage.
- Your heart treatment has been stable for at least 30 days, and a heart ultrasound was done after that stabilization.
- Your symptoms are in the NYHA class II to IVa, and your heart pumping is moderately reduced (ejection fraction 20% to 50%).
- Your mitral valve anatomy is suitable for this edge-to-edge, catheter-based repair, and blood-vessel access for the procedure is feasible.
- You likely have evidence of worsening heart failure (for example, high BNP/NT-proBNP or a heart failure hospitalization in the past 12 months).

This study tests a device called Dragonfly that may reduce mitral regurgitation, a leaky heart valve that can cause shortness of breath and fatigue. The device is placed through a small cut in the leg, avoiding open-heart surgery, and aims to improve symptoms and quality of life.
This trial tests whether repairing a leaky heart valve (mitral valve) can help people with heart failure feel better and live longer, even when standard heart failure medicines are not working well. The repair is done through a small tube in a blood vessel, avoiding open-heart surgery.
This trial tests a new device designed to fix a leaky mitral valve in people with heart failure. It may help you breathe easier and feel less tired if your valve leak is severe and medicines have not been enough.
This trial tests a procedure to fix a leaky mitral valve that occurs because the heart muscle is weak or enlarged, and which gets worse with activity. The procedure aims to reduce the leak and improve symptoms and quality of life in people with heart failure.
This trial tests the safety and effectiveness of a heart procedure that repairs a leaking mitral valve through thin tubes, using the Dragonfly system. It’s for people who have significant mitral valve leak symptoms but are considered high risk for open-heart surgery.
This study tests a new device, called DragonFly M2, to fix a leaky heart valve (mitral valve) that is causing symptoms. The goal is to see if this clip can reduce the leak and improve your heart function.
